LatLonToDistance

public static float LatLonToDistance(float lat1,
                                     float lon1,
                                     float lat2,
                                     float lon2)

Find the distance in km between two points given the lats/lons.

Parameters:

lat1 - - latitude of first point

lat2 - - latitude of second point

lon1 - - longitude of first point

lon2 - - longitude of second point

Returns:

- the distance in km between the two input points

FloatLatLon

public static float FloatLatLon(int dddmmss)

Convert a latitude or longitude in dddmmss format to floating point.

Parameters:

dddmmss - - latitude or longitude

Returns:

- floating point representation of the input parameter.

GouldToNative

public static double GouldToNative(int inVal)

Convert a Gould format floating point number to native double format

Parameters:

inVal - - input Gould value

Returns:

- the input value converted to double floating point

swap

public static void swap(int[] array,
                        int first,
                        int last)

swap the bytes of an integer array

Parameters:

array - array of integers to be flipped

first - starting element of the array

last - last element of array to flip
